Portal for ArcGIS

The installable software component that provides the portal website, sharing model, and built-in identity store. It is one of the four core components and can use built-in accounts or federated identity providers for authentication.

Related: ArcGIS Enterprise portal, Federation, Built-in identity store
ArcGIS Server

The component that hosts and runs GIS services such as map, feature, geoprocessing, and image services. It exposes REST endpoints, manages service lifecycles, and works with the web adaptor and portal to secure access to those services.

Related: ArcGIS Web Adaptor, GIS service, ArcGIS Data Store
ArcGIS Data Store

Software that supplies managed data stores for a hosting server, including the relational store for hosted feature layers, the tile cache store for hosted scene layers, and the spatiotemporal big data store for observational data. It registers with the hosting server it supports.

ArcGIS Web Adaptor

A small web application deployed in a Java or Microsoft servlet container that forwards requests from a friendly URL to portal or ArcGIS Server. It can also enforce web-tier authentication and block direct access to internal component ports.

Related: Reverse proxy, Web-tier authentication, ArcGIS Server
Hosting server

An ArcGIS Server site that has been federated with the portal and configured with a registered ArcGIS Data Store. It publishes and hosts portal-managed layers, so users can create hosted feature, tile, and scene layers without managing services directly.

Related: Federation, ArcGIS Data Store, Hosted feature layer
Federation

The process of connecting an ArcGIS Server site to a portal so the portal becomes the identity provider for that site. After federation, portal accounts and roles govern access to services, and the site can serve as a hosting server.

Related: Hosting server, Named user, Enterprise identity provider
Enterprise identity provider

An external authentication system such as Microsoft Entra ID, LDAP, or SAML-based single sign-on that the portal trusts to verify users. Accounts are managed outside the portal, and group membership can drive role assignment through enterprise groups.

Related: SAML, Enterprise group, Federation
SAML

A standards-based protocol for exchanging authentication and authorization assertions between an identity provider and a service provider. In ArcGIS Enterprise it lets the portal accept single sign-on logins from a trusted identity provider without storing user passwords.

Related: Enterprise identity provider, Single sign-on, Identity provider
Built-in identity store

The default account repository inside Portal for ArcGIS where user names, passwords, and roles are created and maintained directly. It is suitable for small deployments or testing but is usually replaced or supplemented by an enterprise identity provider at scale.

Related: Portal for ArcGIS, Enterprise identity provider, Named user
Named user

A licensed individual account that signs in to the portal and consumes an ArcGIS user type with assigned add-on licenses. Named users are how organizations comply with licensing and control access to apps and capabilities.

Related: User type, Add-on license, Role
User type

A licensing classification that sets the baseline capabilities and entitlement level for a named user, such as viewer, editor, or creator tiers. It determines which apps and functions the account can use before add-on licenses are applied.

Related: Named user, Add-on license
Add-on license

An optional entitlement assigned to a named user or app that unlocks specific capabilities, such as advanced analysis, geocoding, or a particular extension. Add-ons are separate from the user type baseline and are tracked for compliance.

Related: User type, Named user, License file
License file

A signed file issued by the vendor that contains the entitlements and expiration for ArcGIS software. Administrators import it during authorization, and it must be renewed or updated when user counts or add-ons change.

Related: Authorization, Add-on license
Authorization

The step of applying a license file to ArcGIS Server, Portal for ArcGIS, or ArcGIS Data Store so the software runs with the purchased entitlements. Without a valid, unexpired authorization, components refuse to start or operate fully.

Related: License file, ArcGIS Enterprise portal
Role

A set of privileges assigned to portal members that determines what they can do, such as publish content, manage the organization, or administer groups. Custom roles allow fine-grained privilege selection beyond the default role templates.

Related: Privilege, Named user, Group
Privilege

A single permission within the portal's authorization model, such as creating groups or publishing hosted layers. Privileges are bundled into roles, and administrators can combine them to build custom roles that match job duties.

Related: Role, Group
Group

A portal construct that collects members and content for sharing. Content shared to a group is visible only to its members, and group membership can be synchronized from enterprise groups to simplify administration.

Related: Enterprise group, Privilege, Sharing level
Enterprise group

A group in an external identity system that is linked to a portal group so membership is managed automatically. Linking reduces manual effort and keeps access aligned with organizational directory changes.

Related: Enterprise identity provider, Group
Sharing level

The audience setting on portal items, such as private, group, organization, or public. It controls who can discover and use an item, and it works together with service-level permissions to protect content.

Related: Group, Portal item
Portal item

A record in the portal's content store that represents a map, layer, app, or file, along with its metadata, thumbnail, and sharing settings. Items reference services or data and are the unit of sharing and discovery.

Related: Sharing level, Hosted feature layer
Hosted feature layer

A feature layer whose data is stored and managed by the portal's hosting server and relational data store rather than in an external source. Users can edit it, style it, and share it without administrating the underlying service directly.

Related: Hosting server, Relational data store, Portal item
Relational data store

The ArcGIS Data Store role that holds the attribute and geometry records for hosted feature layers and supports querying and editing. It is registered with a hosting server and is essential for hosted feature layer functionality.

Related: ArcGIS Data Store, Hosted feature layer
Tile cache data store

The ArcGIS Data Store role that stores the tiles generated for hosted scene layers and some cached layers. It allows the portal to serve pre-rendered tiles quickly without rebuilding caches on the fly.

Related: ArcGIS Data Store, Hosted scene layer
Spatiotemporal big data store

The ArcGIS Data Store role built on an Elasticsearch cluster that stores high-volume observational and tracking data. It supports GeoEvent and big data analysis workflows that need fast time and space queries.

Related: ArcGIS Data Store, GeoEvent Server
Registered data store

A data source, such as a geodatabase or folder, that an administrator registers with ArcGIS Server so services can reference its data without copying it. Registration enables publishing and lets the server validate data paths.

Related: ArcGIS Server, Hosted feature layer
GIS service

A REST-accessible endpoint published on ArcGIS Server that delivers maps, features, imagery, or geoprocessing results to clients. Services have capabilities, security settings, and instances that administrators configure and monitor.

Related: ArcGIS Server, Service instance
Service instance

A running process on ArcGIS Server that handles requests for a specific service. Administrators set minimum and maximum instance counts to balance responsiveness against memory and CPU consumption.

Related: GIS service, ArcGIS Server
Web-tier authentication

An authentication mode where a reverse proxy or web server in front of ArcGIS components handles login, often via Windows integrated or certificate-based methods. It shifts credential handling to the web tier instead of the GIS tier.

Related: ArcGIS Web Adaptor, Reverse proxy
Reverse proxy

A server that sits in front of ArcGIS components to terminate TLS, route requests, and optionally authenticate users. It improves security and can provide a single entry point for multiple portal or server machines.

Related: ArcGIS Web Adaptor, Web-tier authentication
High availability

A deployment design that keeps the portal and server available when a machine fails, typically through multiple portal machines behind a load balancer and a highly available data store. It requires shared configuration stores and careful failover testing.

Related: Load balancer, ArcGIS Data Store
Load balancer

A network device or service that distributes client requests across multiple portal or server machines. It performs health checks and must be configured to preserve sessions and route traffic consistently for the deployment to work.

Related: High availability, ArcGIS Web Adaptor
Backup

A saved copy of portal content, server configuration, and data store contents used to restore a deployment after failure or corruption. Regular tested backups are essential because some components cannot be rebuilt from scratch.

Related: ArcGIS Data Store, High availability
Log level

A setting that controls how much detail ArcGIS Server and portal components write to logs, from severe errors to verbose debugging. Administrators raise it temporarily to diagnose problems and lower it to control disk usage.

Related: Logs, Service instance
Logs

Recorded messages from ArcGIS components that document errors, warnings, and administrative actions. Reviewing logs is a primary troubleshooting step, and they can be exported or aggregated for centralized monitoring.

Related: Log level, ArcGIS Server
GeoEvent Server

An ArcGIS Server extension that ingests and processes real-time streaming data from sensors and feeds. It can write observations to the spatiotemporal big data store and publish updated layers for live monitoring.

Related: Spatiotemporal big data store, ArcGIS Server
Single sign-on

A login experience where one authentication with an enterprise identity provider grants access to the portal and federated components without re-entering credentials. It depends on trust configured between the identity provider and the portal.

Related: SAML, Enterprise identity provider
Identity provider

The trusted system that authenticates users and issues assertions about their identity to the portal. Configuring its metadata, certificates, and attribute mappings correctly is required for federated logins to succeed.
